Application filed November 6, 1906. Serial No. 342,278.

To all who/s 1, (It TILLLZ/ concern.-

Be it known that I, JOHN H. CoNLEN, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Power-Hammers, of which the following is a specification.

This invention relates to power-hammers of the horizontal type, more particularly to hammers for welding the links of chains; and it consists, essentially, of a sliding carriage mounted upon a frame and carrying a cushioned rammer and an anvil adjacent thereto.

The construction of parts and operation of the machine are more fully described in the following specification and claims, and illustrated in the accompanying drawings, in which Figure 1 is a side elevation of the machine. Fig. 2 is a top plan view thereof. Fig. 3 is a rear end elevation. Fig. 4 is a top plan view of the crank-disk. Fig. 5 is an end view of Fig. 4. Fig. 6 is a top view of the cross-head. Fig. 7 is a side view thereoff Fig. 8 is a perspective view of the ram-guide, and Fig. 9 is a view of the orankpin.

Similar letters and numerals indicate corresponding parts in the different views.

A is the base-plate or foundation, which is substantially of L shape, and B is the standard for supporting the anvil.

C and D are standards supporting the rectangular frame, comprising the carriage guide or way.

E and F are standards supporting the power-shaft G, which carries the disk H.

I is an arm connecting the disk H with the rammer cross-head M of the carriage for imparting movement thereto, and J is the rammer connecting with the carriage and which in its reciprocations hammers against the anvil.

At one end of the base A or on that part I forming the L are two bed-plates 5 and 6,

secured thereto by welding or otherwise. Mounted upon the beds 5 and 6 are the bases 7 and 8 of the standards E and F, said bases being of approximately the same dimensions as the bed-plates 5 and 6 and are secured thereto by bolts 7), for which purpose the beds 5 and 6 and bases 7 and 8 are provided with screw-threaded openings. The standards E and Fare tapered upwardly and at their ends are provided with journal-boxes 9 and 10, consisting, essentially, of two parts,

0 d and ef, ,the loweriones of which, 0 andf, are integral parts of the standards. The parts of the j ournalboxes 9 and 10 are assembled bybolts a.

T 0 one end of the shaft G is the disk H, which is keyed thereto, and at its opposite or rear end the shaft is locked against one same depth as the T-groove, but of less width than the opening in the face of the groove i. The enlargement h gives room for the hand while securing the adjusting-rod to the disk H. The piece between the groove enlarge ment h and the recess 4/ provides a journalbearing j for the adjusting-screw K. Said adjusting-screw is adapted to fit within the groove 1' of the disk H and is provided with screw-threads for adjusting the crank-pin L to regulate the throw of the crank-arm I. The crank-pin L has a head is, adapted to fit loosely and slide freely within the groove i, and is provided with a screw-threaded opening Z, adapted to receive the adjusting-screw K. A locking-nut m secures the crank pin L to its adjusted position, and a sleeve or bushing n, carried by the pin, receives the eye 8 of the crank-arm I. The other end of said crank-arm has a similar eye 9, adapted to pivotally fit between the two lugs 0 of the cross-head m, for which purpose said lugs have openings 0, adapted to register with the. eye 9 of the crank-arm I, and a pin 12 passing through the openings 0 and the eye 9 Bivotally connects the crank I and crossead m.

The rectangular frame constituting the rammer-guideway comprises side pieces 13 and 14 and end pieces 15 and 16, integral with the standards C and D and having their upper surfaces all in the same plane. At

either end of the frame or on each of the pieces 15 and 16 is a spacing-block 17 and 18, of the same width as the end pieces and adapted to support the truss-bars 19 and 20, to which they are secured by the bolts 2]., one of which is at each end of the truss-bars 19 and 20. By means of the spacing-blocks 17 and 18 two guideways 25 and 26 are provided, one on either side of the frame, for the reciprocations of the ramflier-guiding block L and the cross-head M. The cross-head M comprises a block having a recess or perforation to provide a chamber M. One end 40 of said block has an opening to receive the rammer J. Both the cross-hcad M and the rammer-guide L have each two wings, numbered 20 21 and 22 23, respectively, said. wings being oppositely disp'osed and adapted to reciprocate within the ways 25 and 26.

The rammer comprises a shaft, preferably round, and has at its active end a head 27, said head being suitably recessed to receive the hammer block or die 28 and having a mortise behind the head of the die for the in sertion of a drift-pin to drift the die, the end of the hammer die or block being partially cut away to conform to the shape of a chainlink to be welded. The body portion of the shaft J passes through a suitable opening in the spacing-block 17 and carries about midway of its length the rammer-guide L, which is keyed thereto by the integral piece 29 on its inner side, adapted to receive the pin 30. At its rear end the shaft J passes through the opening 31 of the block M and is keyed within the perforation of said. block by the pin 33; but the shaft J is to have free movement through the opening 31 in said block. A cushioning-spring N, carried by the shaft J, between the cross-head M and the rammerguide L, is adapted to contract between those parts and cushion the force of the blow, said contraction being taken up by the move ment of the rammer within the perforation of the cross-head. The standard B is provided at its upper end with a tapered opening in line with the throw of the rammer to receive the pin 3 of the anvil 2, the end of said. pin being threaded to receive nut 4 for securing the anvil to standard 2. The active face of the anvil-block 2 is cut away similar to that of the hammer-block 28.

A treadle 34:, located to one side of the standard C and connected to the source of ower by members 35 and 36, is the means fbr controlling the operation of the machine. In its operation the machine works as follows: Power being applied to the shaft G is transmitted through the disk H and the crank-arm I to the carriage carrying the rammer J and reciprocates the same. When the head 28 of the rammer strikes against the link held by the anvil-block 2, the blow is cushioned and further reinforced by the continued forward movement of the cross-head M against the spring N, which in turn operates against the guide L of the rammer, the rammer-guide L having in the meanwhile stopped with the head 28, the difference in the movements of the cross-head M and ram mer-guide L being taken u by the space within the perforated block it ()ne of the important advantages resulting from the construction herein shown and described resides .in the fact that the anvil and rammer or die are disposed horizontally and low down, so that the operator can always see his work, which is under him, so to speak. Another advantage of importance results from the special construction shown, wherein. the die and anvil are normally widely separated from each other, giving the operator free and unobstructed access to his work. The construction and arrangement of parts also gives the much-desired cushioned blow to the rammer, the force of which may be varied to suit the work by simply adjusting the position of the operating-crank.

A chain-welding machine comprising a frame, an anvil, a carriage within the frame, said carriage comprising a guiding-block and a crosshead, a rammer carried by said carriage, a cushioning means carried bysaid rammer and interposed between the crosshead and the guiding-block, and a powerdriven means operatively connected to said cross-head.
